| | | | | | | | | | | | | | | | | | reasonable amount (currently width * height * 8 bytes), discard all output to the terminal and start trying to redraw periodically instead. Continue with this until the amount of data we are trying to write falls to a low level again. This helps to prevent tmux sitting on a huge buffer of data when there are processes with fast output running inside tmux but the outside terminal is slow. A new client_discarded format holds the amount of data that has been discarded due to this mechanism. The three variables (when to start this, when to stop, and how often to redraw) are basically "works for me" at the moment, this is going in to see how it goes and if it causes problems for anyone else.

* On terminals without DECSLRM, when a pane that is less than the fullnicm2017-04-18
| | | | | | | | | | | | | | | | | | | | | with of the terminal scrolls, tmux needs to redraw the entire pane. This results in a large amount of output data which can cause slow terminals to struggle, particularly when many lines are scrolled together quickly. This can be reduced by only redrawing when tmux doesn't hold any buffered data for the terminal. If a redraw is required and data is buffered, the redraw is deferred until all that data is consumed (it is checked after every event loop, a timer is used to ensure this happens at some point). While a redraw is pending, no additional data will be written to the terminal. The redraw still happens, now it is just pushed back if it is possible it would just add more data on top of a terminal that is already behind. This both gives the terminal a chance to catch up, and allows tmux to process more scrolling (that would require additional redraws) in the meantime. Helps with a problem reported by Greg Hurrell.

* Try again to resolve problems with mistaking sessions for windows: nownicm2017-04-05
| | | | | | | | | | do not look up windows as sessions (and panes as windows) when they are qualified with a ':' or a '.'. So 'foo' as a window target will look for windows and sessions called 'foo', but ':foo' will only look for windows, and 'foo:' only for sessions. This means the common case of using an unadorned session as a window target (send -tfoo) should continue to work, but an explicit window will not get confused with a session (send -t:foo).
* Give each client a name. This defaults to the tty name as before butnicm2017-04-05
| | | | | | | falls back to an alternative if the tty name is not available. This is clearer than overloading the client ttyname member and allows us to remove the path stored in the tty struct, it should always be the same as the client.

* Add support for the strikethrough attribute (SGR 9), using the new smxxnicm2017-03-22
